👩‍🍳 How to Make Keto Garlic Shrimp Au Gratin

1️⃣ Preheat & Prep

Preheat your oven to 375°F (190°C). Lightly grease a small baking dish and set aside.

2️⃣ Sauté the Garlic

In a skillet over medium heat, melt the butter. Add the minced garlic and sauté for about 30 seconds, just until fragrant. (Don’t walk away—garlic burns fast, and burnt garlic is nobody’s friend.)

3️⃣ Add the Cream

Pour in the heavy cream, stirring gently. Let it simmer for 2–3 minutes until slightly thickened. Season with salt, pepper, and red pepper flakes if using.

4️⃣ Add the Shrimp

Add the raw shrimp directly into the creamy garlic sauce. Stir to coat and cook for 2–3 minutes, just until the shrimp start turning pink. They’ll finish cooking in the oven.

5️⃣ Assemble the Au Gratin

Transfer the shrimp and sauce to your prepared baking dish. Sprinkle mozzarella and Parmesan evenly over the top.

6️⃣ Bake Until Golden

Bake uncovered for 15–20 minutes, or until the cheese is bubbly and lightly golden on top.

7️⃣ Garnish & Serve

Sprinkle with fresh parsley and serve hot. Try not to eat it straight from the dish. (Or do. I won’t judge.)

💡 Luma’s Tips for the Best Results

  • Use raw shrimp, not pre-cooked—this keeps them tender, not rubbery
  • Fresh garlic matters here; jarred just won’t give the same flavor
  • Want more sauce? Add an extra splash of cream before baking
  • Extra cheesy fan? Mix a little cheese into the sauce and on top
  • Serving idea: Spoon over zucchini noodles or cauliflower mash
